A pervert who attacked an elderly Harlem woman last year has been linked with the help of DNA to three attempted sex assaults in Miami Beach, police said yesterday.

Investigators believe a sicko involved with the rape and beating of a 68-year-old homeless woman on Aug. 30, 2005, in Harlem is the same man who terrorized women in a string of assaults in Miami Beach in 2004.

DNA and other evidence left behind after the 1 a.m. attack in Riverside Park were fed into a national database and the results were matched this week to DNA from three cases in Florida, police said.

The victims also provided the same description of their attacker – a 5-foot-11 Hispanic man with a muscular build, dark eyes and short, wavy black hair.

Police are unsure of the suspect’s whereabouts.

In 2004, he attacked three women in the Miami Beach area but was fended off, police said.

On April 11, he grabbed and bit a 43-year-old woman. About 25 minutes later, he grabbed and bit a 47-year-old woman, police said. Police ask anyone with information to call Crime Stoppers at (800) 577-TIPS.
